Linked dipoles and EFHW antennas are a really great way to have efficient, resonant, portable antennas that are multi-banded. I’ve never come across a linking method that I really liked. I’ve had b...

I really love loop antennas. In my Delta Loop posts, 1 and 2, I was working with a vertically oriented 20M loop. I found that a 2:1 hybrid balun was a better match than the 4:1 for using it as a mo...

I have always had an interest in Cryptography, ever since reading Simon Singh’s The Code Book. Truly, it is a fascinating area of study and very necessary for secure communications, should the need...

I came across some YouTube posts about the Black Swan Communication Exercise and was intrigued about it. I’ve always been interested in EMCOMMs and it was one of the main reasons I originally becam...

I really wanted to do a repeat test of the Battle of the Baluns to see if the test results were the same. This would add validity to the Voltage Transformer being the better build design. However, ...

Something that has always intrigued me was the controversy about the ever so humble half wave dipole antenna. “Does a dipole need a balun?” And if so, what balun does it need?! YouTube influencer A...

Below is the entire July 15, 2025 Canadian Amateur Radio Exam Question Bank with only the CORRECT answer listed. Link to PDF Version Update: We now have an entire video course available for the B...

I stumbled across what is called the Double Bazooka Antenna. It’s a dipole, also known as the coaxial dipole, and it originated way back in the 1940s when MIT Engineers developed it for the US Gove...

A truly awesome QTH or portable antenna is the Off-Center Fed Dipole. These and variants have been long used by hams to get on the air with added gain. A true multi-band antenna you get 40M, 20M, 1...

The 9:1 UnUn. As a transmission line transformer, you don’t have to have exactly 9 trifilar turns. It depends on core type. The Fatty 43 core does well with only 6 trifilar turns. But regardless, t...
